Apple might not be done apologizing just yet.

Just days after issuing a mea culpa for the lackluster quality of its Maps application for iOS 6, Apple is again acknowledging a problem with its new iPhone: This time, it's a bug that's causing Verizon customers to go through huge amounts of cellular data even though they are connected to a Wi-Fi network.

Commenters have flooded the Apple discussion forums to complain that their iPhones were going through data unusually quickly; now Apple and Verizon have jointly issued a patch to fix the bug. iPhone 5 owners on Verizon are urged to download the patch immediately in the "Settings" section of their iPhone. (Scroll down for complete instructions or visit Apple's website).

Verizon has confirmed to CNN Money that iPhone owners who have been affected by the bug will not be charged for their data overages. If you're a Verizon customer, and you own an iPhone 5, you should definitely check your monthly usage on the Verizon website and make sure that you're not nearing your data cap. You can also check your usage on your iPhone: Go into Settings, then General, then Usage, then Cellular Usage to see how much data you've used so far in your cycle.

Verizon customers aren't the only ones who should be checking in on their monthly usage: 9to5Mac points out that several iPhone 5 owners on AT&T have also complained of excessive data usage in the first weeks with their new phones. AT&T has not yet issued a statement on the supposed bug nor is Apple pushing out a similar patch on AT&T iPhones. An AT&T spokesperson declined to comment.

Apple has an uncomfortable recent history with data overages, especially as it has upgraded its devices to 4G LTE capability. This past March there was a small uproar when the new iPad with 4G LTE was released and owners found themselves eating through their data in record time, due to the faster speeds possible of the LTE network. This new bug appears to be a fault with the software on the phone itself, however, potentially affecting iPhones on every carrier who sells the iPhone, according to the New York Times.

For now, iPhone 5 owners on Verizon are advised to read their mobile phone bills carefully this month and to download Apple's update ASAP. To do so, just follow these steps:

1. Touch Settings, then General, then About.
2. A pop-up balloon that says "Carrier Settings Updated" should appear. Touch OK.
3. Wait for the update to install.
4. Once installation is complete, turn your phone off and then on again in order for it to go into effect.

We'll update this post when we hear more about whether the bug is affecting other carriers. For now, though, if you're an iPhone 5 owner: Keep your eye on your data usage!

Take a look at the gallery (below) to see more of iPhone 5 users' biggest complaints so far.

  • The Maps App Is A Mess

    If you've been following any coverage of the new iPhone, you've heard that iPhone 5 users (or any iDevice users who have updated their gadgets to iOS 6) are complaining rather loudly about how terrible the Apple Maps app is. The new navigation app, which has replaced Google Maps in new versions of iOS, has been seen to <a href="">mislabel cities</a>, <a href="">fail to locate adresses</a> and other problems. Perhaps worst of all (for city-dwellers, at least) the new Maps app <a href="">doesn't provide transit directions</a>, which many became dependent upon with Google Maps.

  • It's TOO Thin And Light

    Given that the new iPhone is touted as Apple's "lightest iPhone ever," the company must be surprised to hear people complaining that it's <em>too</em> light, an issue that <a href="">Gizmodo has noticed users raising on Twitter</a>. "It's following Samsung in the flimsy-feel department," <a href="">writes @befroggled</a>. "Feels like a toy," <a href="">tweeted @HERSEYSDARK</a>. At 112 grams, <a href="">the iPhone 5 is 20 percent lighter</a> than the previous generation, the iPhone 4S.

  • The Updated Siri Is Worse Than Your Local Weatherman

    The new Siri for iOS 6 is sometimes confusing cities with the same name but in different states. (<a href="">A similar problem occurs in the Apple Maps app</a>.) For example, <a href="">MacRumors noticed</a> that asking for the weather in New York City yields temperatures and forecasts for New York, Texas. Siri is similarly mixing up the St. Louises in Missouri and Georgia and the Carrolltons in Texas and Indiana.

  • Battery Life Seems Sub-Par For Some

    Every new iPhone brings <a href="">complaints about battery life</a>. <a href="">(Read more about about the iPhone 4S's battery weakness here.)</a> "horrible battery life, i am disgusted," <a href="">mht83193 wrote on an Apple discussion thread</a>. He describes losing 40 percent of his fully-charged iPhone battery in one hour. Are people's iPhone batteries just be draining faster because of overuse, a new energy-sucking app or a glitch in iOS 6? During the key presentation on the iPhone 5, Apple claimed <a href="">the iPhone 5 got 225 hours of battery life while on standby</a>, compared to 200 for the iPhone 4S. If you're having battery life issues with the iPhone 5, we recommend <a href="">reading the blog iMore's troubleshooting guide</a>.

  • It 'Leaks' Light

    While white iPhone 5s are apparently not as easy to scuff as the black models, the white models have another problem of their own: A a tiny amount of light leaks out of the top right corner of the device's screen. The light leak can be see when they screen is activated in a dark room, <a href="">according to complaints at MacRumors</a>. The tech blog <a href="">BGR confirms the "light leak" with its own phones</a>. The iPad 2 reportedly had a similar problem in 2011, <a href="">according to CNET.</a> [<a href="">photo via MacRumors</a>]

  • It Scratches Too Easily

    When you drop several hundred on a new iPhone, you want it to be pristine. That's what makes the so-called "scuff-gate" controversy such a blemish on the reputation of a company as obsessed with design as Apple. <a href="">Bloggers at AllThingsD</a> and <a href="">posters on the MacRumor forums</a> complain that the black iPhone 5 is very susceptible to dings and scratches, perhaps due to the iPhone 5's aluminum casing (which didn't exist on previous iPhones). Watch a 2-year-old girls scuff up a perfectly good iPhone 5 to the right, <a href="">in a video from iFixIt</a>.

  • It's Got A Screw Loose? (Well, Not A Screw)

    <em>Rattle, rattle.</em> That's the sounds some iPhone 5 owners get when they shake their device, <a href="">according to posts on the forums</a>. Some claim being told by Apple that it's normal noise created by camera competents, other say it's an unglued battery (the latter problem can be fixed with a trip to an Apple Store). In either case, it's annoying, as numerous YouTube videos show.

  • Its WiFi Radio Is Finicky

    Again, Internet forums have been lighting up about slow to nonexistent WiFi connectivity in their new iPhones, when compared to the iPhone 4 or 4S. <a href="">MacRumor writes</a <a href="">(and posts on the Apple Forums confirm)</a> that the issue for some users has to do with using a certain secure WiFi connection called WPA2. Moving to less secure WiFi connections resolves the issue, according to forums.

  • The 'No SIM Card Installed' Error

    This is annoying: Imagine buying an iPhone, putting your SIM card in it and being told by your phone that there's "no SIM card installed." That's the error message reported in forums <a href="">here</a> and <a href="">here</a>. If you're having this problem, restart your phones by holding down the Home and Sleep buttons. If that doesn't help, take it to the Apple Store and they can replace your SIM Card.
